Coronary Physiology in Patients with Stable and Unstable Coronary Artery Disease - Evaluation of Instantaneous Wave-Free Ratio
Background: Revascularization of a stenosis is warranted when hemodynamically significant. Coronary physiology provides a diagnostic tool for assessment of stenosis severity to aid in the decision to revascularize or defer. The iFR-SWEDEHEART trial demonstrated non-inferiority of the instantaneous wave-free ratio (iFR) compared to fractional flow reserve (FFR) in guiding decision-making in coronar
